Application manner and fundamental structure of the fundamental structure in the structure

摘要

PPROBLEM TO BE SOLVED: To provide a method of constructing foundation in a structure, capable of increasing coupling force between a foundation member constructed on a pile body and the pile body, capable of enhancing construction performance of the pile body, capable of reducing a construction cost by reducing a diameter of the pile body, capable of enhancing quality of the pile body, by using no stabilization liquid, and capable of enhancing earthquake resistance, horizontal resistance and the like by pseudo-increase of the diameter of the pile body, and by a lattice-like improved ground, and the foundation structure. PSOLUTION: A wall-like improved ground 2 is constructed lattice-likely within a soft ground 1, and then the pile body 6 is constructed integrally with the improved ground 2 in a crossed part of the lattice-like improved ground 2, by an earth drill construction method as a cast-in-place pile construction method.
